Matthew Vaughn, who helmed X-Men: First Class after taking over directorial duties from previous X-Men Film series director Bryan Singer, will be abdicating the directors chair of the upcoming First Class sequel, X-Men: Days of Future Past to direct a film adaptation of Secret Service, a project he co-produced with Mark Millar.

Vaughn had worked on the 2010 film adaptation of Millar’s Kick-Ass comic series.

There is speculation that the short list for a replacement director for Days of Future Past would be no other than… Bryan Singer, who also served as a producer for the previous film, and was supposed to take the reigns over from Vaughn at some point in one of the First class trilogy films anyway.
